Space Seed.
Clue #1 The loss of a dozen seems no cause for concern.
Twelve life support units failed yet Khan never bats an eye on hearing this. He seems only concerned about reviving those that did survive.
Clue #2 Half a dozen per seven, which is a bad rhyme but a good ratio ... considering.
There were 72 units still working out of 84 total units. Ratio 72:84 or 6:7 (6x12=72, 7x12=84).
Clue #3 Survivors, like five out of seven in "Galileo Seven"
They are survivors.
Clue #4 Those previous numbers are important, but I'm still upset at being shown only one per every ten of those golden ones.
Not enough of the 30 women are shown?
Clue #5 The ratio 5 to 7 does have significance in this episode also, but not as a survival ratio. After survival, it's "5 women - for every 7 men". Also a bad rhyme but this time not a good ratio. What about the lost dozen? I have no stats on them.
There are 72 remaining units, 30 of which are female, which makes 42 male. Therefore, 5 to 7. We are given no info on the make-up of the twelve that fail.
Clue #6 Instead of throwing more ratios and other stats at you, let's pause and consider the numbers so far. Can we calculate anything with the numbers given? Sometimes ratios obscure the truth in the data, and the absolute total numbers are more meaningful and obvious. I suspect that after a long day of work, no one was in the mood to actually do some of the possible calculations.
Clue #7 After giving so much data, I'm starting to wonder if some of it is redundant, but on review I think not. Still, when this is all over, I feel I will need to apologize for being repetitive.
Admonishments rather than clues I think LOL
